New Guinea Impatiens plant named ‘Tamar Pink’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Tamar Pink’, characterized by its dark pink-colored flowers; freely flowering habit with flowers positioned above or beyond the foliage; upright, somewhat outwardly spreading, rounded, uniform and compact plant habit; freely branching growth habit; and glossy dark green leaves.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name Tamar Pink.

The new Impatiens is a product of a planned breeding program Inventor in Maasland, The Netherlands. The objective of the breeding program is to develop new Impatiens cultivars with uniform plant habit and attractive flower and foliage colors.

The new Impatiens originated from a cross made by the Inventor in 1997 of the Impatiens hawkeri cultivar Grenada, disclosed in U.S. Plant Pat. No. 9,343, as the male, or pollen parent, with the Impatiens hawkeri cultivar Hudson, not patented, as the female, or seed parent. The cultivar Tamar Pink was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Maasland, The Netherlands in 1997.

Asexual reproduction of the new cultivar by terminal cuttings taken at Maasland, The Netherlands, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tamar Pink’. These characteristics in combination distinguish ‘Tamar Pink’ as a new and distinct Impatiens cultivar:

1. Dark pink-colored flowers.

2. Freely flowering habit with flowers positioned above or beyond the foliage.

3. Upright, somewhat outwardly spreading, rounded, uniform and compact plant habit.

4. Freely branching growth habit.

5. Glossy dark green leaves.

In side-by-side comparisons conducted by the Inventor in Maasland, The Netherlands, plants of the new Impatiens differ primarily from plants of the male parent, the cultivar Grenada, in flower color as flower color of plants of the cultivar Grenada is salmon pink.

In side-by-side comparisons conducted by the Inventor in Maasland, The Netherlands, plants of the new Impatiens differ primarily from plants of the female parent, the cultivar Hudson, in growth habit as plants of the new Impatiens are more uniform and more compact than plants of the cultivar Hudson.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Tamar Pink’ grown in a 12.5-cm container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Tamar Pink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, water status and fertility level, without, however, any variance in genotype. The following observations and measurements describe plants grown in Maasland, The Netherlands, during the early autumn, under commercial practice in a glass-covered greenhouse. Plants used in the following description were about 10 to 12 weeks old from planting rooted cuttings and grown in 12.5-cm containers with one plant per container.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
